Pros and Cons of Buying a Speedway 91015301 Cheater Crank Flange for a 1986 Chevy

The Speedway 91015301 Cheater Crank Flange is a replacement part designed for use in the crankshaft of certain 1980s Chevy engines. This component is sometimes sought out by automotive enthusiasts looking to modify their engines for improved performance. Here are some potential advantages and disadvantages to consider before purchasing this part.

1. Improved Performance: The cheater crank flange can help increase engine performance by allowing for a larger crankshaft stroke, which results in increased displacement and more power output.

2. Cost-Effective: Compared to other methods of achieving a larger crankshaft stroke, such as stroker kits or forged cranks, the cheater crank flange is often a more affordable option.

3. Easy Installation: The cheater crank flange is typically a straightforward installation process, requiring only basic hand tools and minimal engine disassembly.

1. Potential Engine Damage: Installing a cheater crank flange can potentially cause engine damage if not done correctly. Improperly torqued crankshaft bolts or incorrect installation of the new flange can lead to catastrophic engine failure.

2. Reduced Reliability: The cheater crank flange is not a factory-designed component and may not be as robust as the original equipment. This could lead to reduced engine reliability and an increased likelihood of future issues.

3. Potential for Noise and Vibration: Installing a cheater crank flange can potentially result in increased engine noise and vibration due to the added stress on the crankshaft and connecting rods.

The decision to purchase a Speedway 91015301 Cheater Crank Flange for a 1986 Chevy ultimately depends on your individual goals and priorities. If you're looking for a cost-effective way to increase engine performance, this part may be worth considering. However, it's essential to weigh the potential risks against the benefits and ensure that the installation is performed correctly to minimize the chance of engine damage.

If you decide to pursue the installation of a cheater crank flange, we recommend consulting a professional mechanic or engine builder to ensure the installation is carried out safely and correctly. This will help minimize the risks associated with the modification and maximize the potential benefits. Additionally, consider investing in high-quality installation tools and torque wrenches to ensure the bolts are torqued correctly.
